The first hard freeze in St. Louis usually brings a wave of calls about furnaces, frozen pipes, and utility bills. For landlords, it also brings rules that shape what happens when a tenant falls behind on heating costs.
Missouri’s Cold Weather Rule runs from November 1 through March 31 every year. Here is how it works, what changed recently, and what it means for your rental properties.
Key Takeaways
- The Cold Weather Rule runs from November 1 through March 31 and has been part of Missouri Public Service Commission rules since 1977.
- It limits disconnection of heat-related gas and electric service when temperatures are forecast to drop below 32 degrees.
- A 2025 state law extended the forecast window from 24 hours to 72 hours.
- It only applies to utilities regulated by the PSC, not municipal systems, cooperatives, or propane delivery.
- Landlords should never cut off utilities to force a tenant out, and should keep vacant units heated.
What the Cold Weather Rule Does
The Missouri Public Service Commission’s Cold Weather Rule is designed to protect customers from losing heat during the coldest months. Among its key protections, according to PSC materials:
- Utilities cannot disconnect heat-related service when the temperature is forecast to drop below 32 degrees during the protected window.
- Customers can budget payments over 12 months.
- Utilities must mail a notice 10 days before a planned shutoff.
- More lenient payment terms can allow service to be reconnected for less than the full balance.
- Registered elderly and disabled customers receive added protections.
What Changed in 2025
A utility law passed by the Missouri legislature in 2025 extended the temperature window. Utilities can no longer disconnect heat service if temperatures are forecast to fall below 32 degrees within the next 72 hours, up from 24 hours, as reported by KBIA (December 22, 2025).

The 2026 to 2027 season will be the second winter under the 72-hour window. Utilities can still resume shutoff notices when temperatures warm up, so the rule delays disconnections rather than erasing a customer’s balance.
Which Utilities Are Covered
The rule applies only to investor-owned natural gas and electric utilities under PSC jurisdiction. Municipally operated systems, electric cooperatives, and propane delivered by truck are not covered.
| Utility type | Covered by the Cold Weather Rule? |
|---|---|
| Investor-owned natural gas and electric utilities under PSC jurisdiction | Yes |
| Municipally operated systems | No |
| Electric cooperatives | No |
| Propane delivered by truck | No |
If your rental uses a co-op or propane for heat, check that provider’s own policies. Tenants in those homes may not have the same protections.
What the Rule Means for Landlords
In most St. Louis rentals, tenants hold utility accounts in their own names. The Cold Weather Rule protects them as customers, but it does not change what they owe you under the lease.
If a tenant falls behind, the utility handles collections and any shutoff under PSC rules. Encourage tenants to contact the utility early about payment plans.
If you pay heating costs, keep accounts current. A lapse could leave tenants without heat and may put the property at risk.
Keep heat on at a safe setting during vacancies to prevent frozen and burst pipes.
Missouri does not allow landlords to use self-help to remove a tenant, and interrupting utilities to force someone out can create serious legal liability. If a tenant is behind on rent, follow the court process instead.
Talking With Tenants About Winter Bills
Heating bills can rise sharply in January and February, and a tenant who falls behind on utilities may soon fall behind on rent. A little communication in the fall can help.
- Share tips for lowering heating costs, such as sealing drafts and using programmable thermostats.
- Point tenants to their utility’s budget billing and payment plan options.
- Share information about local energy assistance programs, such as LIHEAP, when available.
- Ask tenants to report drafty windows or doors so you can fix them early.
Energy efficiency upgrades also help your property. Weatherstripping, attic insulation, and furnace maintenance can lower bills and make your rental more attractive to future tenants.
